# CVE-2025-25283: parse-duraton vulnerable to Regex Denial of Service that results in event loop delay and out of memory

- Also known as: GHSA-HCRG-FC28-FCG5
- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2.1.3
- Published: 2025-02-12 · Updated: 2025-02-12

## Affected

- jkroso parse-duration: fixed in 2.1.3
- parse-duration (npm): fixed in 2.1.3

## Description

parse-duraton is software that allows users to convert a human readable duration to milliseconds. Versions prior to 2.1.3 are vulnerable to an event loop delay due to the CPU-bound operation of resolving the provided string, from a 0.5ms and up to ~50ms per one operation, with a varying size from 0.01 MB and up to 4.3 MB respectively, and an out of memory that would crash a running Node.js application due to a string size of roughly 10 MB that utilizes unicode characters. Version 2.1.3 contains a patch.

## What to do

- Check your stack: if you ship or depend on jkroso parse-duration, parse-duration, upgrade to a fixed version (2.1.3) per the references below.
